The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2024:1614 advisory.

  - Integer Overflow or Wraparound vulnerability in openEuler kernel on Linux (filesystem modules) allows     Forced Integer Overflow.This issue affects openEuler kernel: from 4.19.90 before 4.19.90-2401.3, from     5.10.0-60.18.0 before 5.10.0-183.0.0. (CVE-2021-33631)

  - A NULL pointer dereference vulnerability was found in vmwgfx driver in drivers/gpu/vmxgfx/vmxgfx_execbuf.c     in GPU component of Linux kernel with device file '/dev/dri/renderD128 (or Dxxx)'. This flaw allows a     local attacker with a user account on the system to gain privilege, causing a denial of service(DoS).
    (CVE-2022-38096)

  - In the Linux kernel before 6.4.12, amdgpu_cs_wait_all_fences in drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c has     a fence use-after-free. (CVE-2023-51042)

  - A race condition was found in the GSM 0710 tty multiplexor in the Linux kernel. This issue occurs when two     threads execute the GSMIOC_SETCONF ioctl on the same tty file descriptor with the gsm line discipline     enabled, and can lead to a use-after-free problem on a struct gsm_dlci while restarting the gsm mux. This     could allow a local unprivileged user to escalate their privileges on the system. (CVE-2023-6546)

  - A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be     exploited to achieve local privilege escalation. A perf_event's read_size can overflow, leading to an heap     out-of-bounds increment or write in perf_read_group(). We recommend upgrading past commit     382c27f4ed28f803b1f1473ac2d8db0afc795a1b. (CVE-2023-6931)

  - An out-of-bounds memory read flaw was found in receive_encrypted_standard in fs/smb/client/smb2ops.c in     the SMB Client sub-component in the Linux Kernel. This issue occurs due to integer underflow on the memcpy     length, leading to a denial of service. (CVE-2024-0565)

  - A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. The nft_verdict_init() function allows positive values as drop error     within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when     NF_DROP is issued with a drop error which resembles NF_ACCEPT. We recommend upgrading past commit     f342de4e2f33e0e39165d8639387aa6c19dff660. (CVE-2024-1086)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Integer Overflow or Wraparound vulnerability in openEuler kernel on Linux (filesystem modules) allows     Forced Integer Overflow.This issue affects openEuler kernel: from 4.19.90 before 4.19.90-2401.3, from     5.10.0-60.18.0 before 5.10.0-183.0.0. (CVE-2021-33631)

  - An issue was discovered in drivers/input/input.c in the Linux kernel before 5.17.10. An attacker can cause     a denial of service (panic) because input_set_capability mishandles the situation in which an event code     falls outside of a bitmap. (CVE-2022-48619)

  - In the Linux kernel before 6.4.12, amdgpu_cs_wait_all_fences in drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c has     a fence use-after-free. (CVE-2023-51042)

  - In the Linux kernel before 6.4.5, drivers/gpu/drm/drm_atomic.c has a use-after-free during a race     condition between a nonblocking atomic commit and a driver unload. (CVE-2023-51043)

  - In the Linux kernel, the following vulnerability has been resolved: net: prevent mss overflow in     skb_segment() Once again syzbot is able to crash the kernel in skb_segment() [1] GSO_BY_FRAGS is a     forbidden value, but unfortunately the following computation in skb_segment() can reach it quite easily :
    mss = mss * partial_segs; 65535 = 3 * 5 * 17 * 257, so many initial values of mss can lead to a bad final     result. Make sure to limit segmentation so that the new mss value is smaller than GSO_BY_FRAGS.

  - In the Linux kernel, the following vulnerability has been resolved: uio: Fix use-after-free in uio_open     core-1 core-2 ------------------------------------------------------- uio_unregister_device uio_open idev     = idr_find() device_unregister(&idev->dev) put_device(&idev->dev) uio_device_release     get_device(&idev->dev) kfree(idev) uio_free_minor(minor) uio_release put_device(&idev->dev) kfree(idev)
    ------------------------------------------------------- In the core-1 uio_unregister_device(), the     device_unregister will kfree idev when the idev->dev kobject ref is 1. But after core-1 device_unregister,     put_device and before doing kfree, the core-2 may get_device. Then: 1. After core-1 kfree idev, the core-2     will do use-after-free for idev. 2. When core-2 do uio_release and put_device, the idev will be double     freed. To address this issue, we can get idev atomic & inc idev reference with minor_lock.
    (CVE-2023-52439)

  - In the Linux kernel, the following vulnerability has been resolved: gfs2: Fix kernel NULL pointer     dereference in gfs2_rgrp_dump Syzkaller has reported a NULL pointer dereference when accessing rgd->rd_rgl     in gfs2_rgrp_dump(). This can happen when creating rgd->rd_gl fails in read_rindex_entry(). Add a NULL     pointer check in gfs2_rgrp_dump() to prevent that. (CVE-2023-52448)

  - An out-of-bounds access vulnerability involving netfilter was reported and fixed as: f1082dd31fe4     (netfilter: nf_tables: Reject tables of unsupported family); While creating a new netfilter table, lack of     a safeguard against invalid nf_tables family (pf) values within `nf_tables_newtable` function enables an     attacker to achieve out-of-bounds access. (CVE-2023-6040)

  - An out-of-bounds read vulnerability was found in the NVMe-oF/TCP subsystem in the Linux kernel. This issue     may allow a remote attacker to send a crafted TCP packet, triggering a heap-based buffer overflow that     results in kmalloc data being printed and potentially leaked to the kernel ring buffer (dmesg).
    (CVE-2023-6121)

  - A Null pointer dereference problem was found in ida_free in lib/idr.c in the Linux Kernel. This issue may     allow an attacker using this library to cause a denial of service problem due to a missing check at a     function return. (CVE-2023-6915)

  - A memory leak problem was found in ctnetlink_create_conntrack in net/netfilter/nf_conntrack_netlink.c in     the Linux Kernel. This issue may allow a local attacker with CAP_NET_ADMIN privileges to cause a denial of     service (DoS) attack due to a refcount overflow. (CVE-2023-7192)

  - A vulnerability was found in vhost_new_msg in drivers/vhost/vhost.c in the Linux kernel, which does not     properly initialize memory in messages passed between virtual guests and the host operating system in the     vhost/vhost.c:vhost_new_msg() function. This issue can allow local privileged users to read some kernel     memory contents when reading from the /dev/vhost-net device file. (CVE-2024-0340)

  - An out-of-bounds memory read flaw was found in receive_encrypted_standard in fs/smb/client/smb2ops.c in     the SMB Client sub-component in the Linux Kernel. This issue occurs due to integer underflow on the memcpy     length, leading to a denial of service. (CVE-2024-0565)

  - A flaw was found in the Netfilter subsystem in the Linux kernel. The issue is in the nft_byteorder_eval()     function, where the code iterates through a loop and writes to the `dst` array. On each iteration, 8 bytes     are written, but `dst` is an array of u32, so each element only has space for 4 bytes. That means every     iteration overwrites part of the previous element corrupting this array of u32. This flaw allows a local     user to cause a denial of service or potentially break NetFilter functionality. (CVE-2024-0607)

  - A denial of service vulnerability due to a deadlock was found in sctp_auto_asconf_init in     net/sctp/socket.c in the Linux kernel's SCTP subsystem. This flaw allows guests with local user privileges     to trigger a deadlock and potentially crash the system. (CVE-2024-0639)

  - A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. The nft_verdict_init() function allows positive values as drop error     within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when     NF_DROP is issued with a drop error which resembles NF_ACCEPT. We recommend upgrading past commit     f342de4e2f33e0e39165d8639387aa6c19dff660. (CVE-2024-1086)

  - In the Linux kernel, the following vulnerability has been resolved: tls: fix race between tx work     scheduling and socket close Similarly to previous commit, the submitting thread (recvmsg/sendmsg) may exit     as soon as the async crypto handler calls complete(). Reorder scheduling the work before calling     complete(). This seems more logical in the first place, as it's the inverse order of what the submitting     thread will do. (CVE-2024-26585)

  - In the Linux kernel, the following vulnerability has been resolved: mlxsw: spectrum_acl_tcam: Fix NULL     pointer dereference in error path When calling mlxsw_sp_acl_tcam_region_destroy() from an error path after     failing to attach the region to an ACL group, we hit a NULL pointer dereference upon 'region->group->tcam'     [1].

  - When a router encounters an IPv6 packet too big to transmit to the next-hop, it returns an ICMP6 'Packet     Too Big' (PTB) message to the sender. The sender caches this updated Maximum Transmission Unit (MTU) so it     knows not to exceed this value when subsequently routing to the same host. (CVE-2023-52340)

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Integer Overflow or Wraparound vulnerability in openEuler kernel on Linux (filesystem modules) allows     Forced Integer Overflow.This issue affects openEuler kernel: from 4.19.90 before 4.19.90-2401.3, from     5.10.0-60.18.0 before 5.10.0-183.0.0. (CVE-2021-33631)

  - An issue was discovered in drivers/input/input.c in the Linux kernel before 5.17.10. An attacker can cause     a denial of service (panic) because input_set_capability mishandles the situation in which an event code     falls outside of a bitmap. (CVE-2022-48619)

  - In the Linux kernel before 6.4.12, amdgpu_cs_wait_all_fences in drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c has     a fence use-after-free. (CVE-2023-51042)

  - In the Linux kernel before 6.4.5, drivers/gpu/drm/drm_atomic.c has a use-after-free during a race     condition between a nonblocking atomic commit and a driver unload. (CVE-2023-51043)

  - In the Linux kernel, the following vulnerability has been resolved: net: prevent mss overflow in     skb_segment() Once again syzbot is able to crash the kernel in skb_segment() [1] GSO_BY_FRAGS is a     forbidden value, but unfortunately the following computation in skb_segment() can reach it quite easily :
    mss = mss * partial_segs; 65535 = 3 * 5 * 17 * 257, so many initial values of mss can lead to a bad final     result. Make sure to limit segmentation so that the new mss value is smaller than GSO_BY_FRAGS.

  - In the Linux kernel, the following vulnerability has been resolved: uio: Fix use-after-free in uio_open     core-1 core-2 ------------------------------------------------------- uio_unregister_device uio_open idev     = idr_find() device_unregister(&idev->dev) put_device(&idev->dev) uio_device_release     get_device(&idev->dev) kfree(idev) uio_free_minor(minor) uio_release put_device(&idev->dev) kfree(idev)
    ------------------------------------------------------- In the core-1 uio_unregister_device(), the     device_unregister will kfree idev when the idev->dev kobject ref is 1. But after core-1 device_unregister,     put_device and before doing kfree, the core-2 may get_device. Then: 1. After core-1 kfree idev, the core-2     will do use-after-free for idev. 2. When core-2 do uio_release and put_device, the idev will be double     freed. To address this issue, we can get idev atomic & inc idev reference with minor_lock.
    (CVE-2023-52439)

  - An out-of-bounds access vulnerability involving netfilter was reported and fixed as: f1082dd31fe4     (netfilter: nf_tables: Reject tables of unsupported family); While creating a new netfilter table, lack of     a safeguard against invalid nf_tables family (pf) values within `nf_tables_newtable` function enables an     attacker to achieve out-of-bounds access. (CVE-2023-6040)

  - An out-of-bounds read vulnerability was found in the NVMe-oF/TCP subsystem in the Linux kernel. This issue     may allow a remote attacker to send a crafted TCP packet, triggering a heap-based buffer overflow that     results in kmalloc data being printed and potentially leaked to the kernel ring buffer (dmesg).
    (CVE-2023-6121)

  - A memory leak problem was found in ctnetlink_create_conntrack in net/netfilter/nf_conntrack_netlink.c in     the Linux Kernel. This issue may allow a local attacker with CAP_NET_ADMIN privileges to cause a denial of     service (DoS) attack due to a refcount overflow. (CVE-2023-7192)

  - A vulnerability was found in vhost_new_msg in drivers/vhost/vhost.c in the Linux kernel, which does not     properly initialize memory in messages passed between virtual guests and the host operating system in the     vhost/vhost.c:vhost_new_msg() function. This issue can allow local privileged users to read some kernel     memory contents when reading from the /dev/vhost-net device file. (CVE-2024-0340)

  - An out-of-bounds memory read flaw was found in receive_encrypted_standard in fs/smb/client/smb2ops.c in     the SMB Client sub-component in the Linux Kernel. This issue occurs due to integer underflow on the memcpy     length, leading to a denial of service. (CVE-2024-0565)

  - A flaw was found in the Netfilter subsystem in the Linux kernel. The issue is in the nft_byteorder_eval()     function, where the code iterates through a loop and writes to the `dst` array. On each iteration, 8 bytes     are written, but `dst` is an array of u32, so each element only has space for 4 bytes. That means every     iteration overwrites part of the previous element corrupting this array of u32. This flaw allows a local     user to cause a denial of service or potentially break NetFilter functionality. (CVE-2024-0607)

  - A denial of service vulnerability due to a deadlock was found in sctp_auto_asconf_init in     net/sctp/socket.c in the Linux kernel's SCTP subsystem. This flaw allows guests with local user privileges     to trigger a deadlock and potentially crash the system. (CVE-2024-0639)

  - A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. The nft_verdict_init() function allows positive values as drop error     within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when     NF_DROP is issued with a drop error which resembles NF_ACCEPT. We recommend upgrading past commit     f342de4e2f33e0e39165d8639387aa6c19dff660. (CVE-2024-1086)

  - When a router encounters an IPv6 packet too big to transmit to the next-hop, it returns an ICMP6 'Packet     Too Big' (PTB) message to the sender. The sender caches this updated Maximum Transmission Unit (MTU) so it     knows not to exceed this value when subsequently routing to the same host. (CVE-2023-52340)
